Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541050, here are decompositions:

3 + 31541047 = 31541050
11 + 31541039 = 31541050
29 + 31541021 = 31541050
59 + 31540991 = 31541050
71 + 31540979 = 31541050
89 + 31540961 = 31541050
179 + 31540871 = 31541050
227 + 31540823 = 31541050

Showing the first eight; more decompositions exist.
